The invention relates to solar technology, in particular, to inflatable focusing solar collectors. An inflatable focusing solar collector is known, comprising a tubular radiation detector, a support frame mounted thereon with a casing made of an optically transparent elastic material and provided with a mirror coating on the inside, and an orientation drive associated with a tubular radiation detector Lj, Lime Solar Collector , the orientation drive of which has an electronic device, is located outside the collector and is structurally complex. The purpose of the invention is to ensure the autonomy of the orientation and simplification. design The goal is achieved by the fact that in an inflatable focusing solar collector containing a tubular radiation detector, a support frame mounted on it with a worn on. with a casing made of an optically transparent elastic material and provided with a mirror coating from the inside, and an orientation drive associated with a tubular radiation detector, the support frame is provided with a bracket and is rotatably mounted with respect to the receiver, the end edges of the casing are germically fixed to the latter using a bandage, and the drive orientation is located inside the casing and is made in the form of two bimetallic plates symmetrically located relative to the receiver, one end of each of which is fixed to The other is not, and the other is at the radiation receiver. On fi. 1 shows an inflatable focusing solar collector; in fig. 2 - the same. Cross section with a beam path. The inflatable focusing solar collector contains a tubular radiation receiver 1 (FIG. 1) mounted on. There is a support frame 2 with a casing 3 put on it, made of an optically transparent material and provided with a mirror coating 4 from the inside (Fig. 2), and an orientation actuator 5 connected to the tubular radiation receiver 1. The support frame 2 is provided with a bracket 6 and is rotatably mounted relative to the receiver 1, the end edges of the casing 3 (FIG. 1) are sealed to the latter with a band 7, and the orientation drive 5 is located inside the casing 3 and is symmetrically located relative to the receiver 1 two bimetallic plates 8, one end of each of which is fixed on the bracket 6, and the other on the receiver 1 radiation. Inflatable focusing solar collector works as follows. A solar collector with cooled bimetallic plates 8 (FIG. 1) is installed with an optical axis directed to Zenith. At sunrise, one of the plates 8 (Fig. 2) is heated by the action of the sun's rays reflected by the specular coating 4 and, deformed, causes rotation of the support frame 2 relative to the radiation receiver 1. In this case, radiation is redistributed between the plasma; 8, balancing the forces they develop and stopping the movement of the pa. We are 2 with a casing 3. The movement of the Sun is accompanied by an imbalance of forces in the bimetallic plates 8 and a turn of the frame 2 with a casing 3. After the sun goes down, the plates. 8 cool down, acquire the original shape and return the solar collector to its original position. Performing the orientation actuator 5 in the form of bimetallic plates 8 located in the focal zone of the solar collector allows for autonomic orientation, simplifying the design of the actuator and eliminating backlash in it.
